As far as Stainsheild gores consider this:
Several manufacturers claim to have a carpet protector built into their product. I have a problem with this. Some protectors come pre-mixed but most mix 1:1 or 1: 3. That’s one gallon of concentrate at a cost of $40 to $50 dollars per gallon of concentrate on average.
Now a cleaning product manufacturer wants you to believe that their $30 dollar a gallon product, that mixes only 6 ounces of concentrate into a gallon of water, has enough chemical protector in it to be effective. Don’t forget they also need room for the polymers, detergents, surfactants and so on. Even the straight six ounces of concentrate would not be enough, let alone reducing it further by adding the other ingredients and water that’s already in the encaps formula before it is diluted into the gallon of water. The math simply does not support this if you think about it.
